buckles 16 near the ends of the supports 11 and extending from one support to the second one below as most clearly shown in Figs. and 6. The supports 11 are preferably installed so that alternate ones will be staggered with respect to each other, as shown in Fig. 5. By means of the turn-buckles 16, a row of tubes may be sprung upwardly to the positions shown in the broken. lines in Figs. 5 and 6, thus leaving room between the lower legs of these tubes and the upper legs of the lower row of tubes for a tube to be,

withdrawn sidewise, as shown by broken lines in Figs. 5 'an'd 6. The bar 11 and spacing strip 14 are removed fromthe row of tube that is tobe removed is disconnected from the headers and is moved longitudinally until its free ends pass out of the holes in the support 6, after which the tube is maneuveredinto the lane and in so doingthe tube is turned until its legs are in a horizontal plane, and then it is moved sidewise through the lane which has been enlarged, as ex- M plained above, by springing the return bend ends of the upper row of tubes upwardly} A- new tube is then maneuvered into place from which the injured tube was removed,

through the slots 12 and then lifting up-' wardly on this service bar'by means of a turn-buckle similar to that above described. After the bar 11 and spacing strip 14 have been replaced, the turn-buckle isremoved and the service bar withdrawn, whereupon the upper sides of the tubes 2 drop into the notches onthe spacing strip 14:.

I/Vhen the tubes extend through the .plate 6 as shown in F ig; 3, the bent ends of the tubes can be raised slightly farther after the upper sides of the legs 2 come into contact with the upper edges of the holes 7 before the upper sides of the legs 3 contact with the upper edges of the holes 8. In the modification shown in Fig. 4 the distance through which the bent ends of the tubes can be raised before the upper sides of the lower legs 3 come into contact with the plate 6is considerably greater than in Fig. 3. The slots 8 do not seriously weaken the plate support 6 and their presence avoids the necessity of givingthe lower legs 3 of the tubes compara bent ends 4 of the tubes are raised.
